IPA: //ˈbɜːɡlərɪəs//
KK: /ˈbɜrɡlərɪəs/
Relating to the crime of breaking into a building to commit theft.
The police are investigating a series of burglarious activities in the neighborhood.
Burglarious → It is formed from "burglar" (from Old French *burglar*, meaning a thief who breaks into a house) and the suffix "-ious" (meaning full of or characterized by). The word "burglarious" describes something that is characteristic of or pertaining to burglary or theft.
Think of a 'burglar' as someone who breaks into a place, and the '-ious' means full of that quality — so burglarious refers to something full of burglary.
